I removed .env file, what should I do?

I moved all the Umbrel4.0 files to a new directory but forgot the hide file .env, then I removed the old directory. now, I run ./script/start, the Umbel can not work , I have sync some blocks already.
What is the best way to recover?

I fixed the problem, just remove the file(./statuses/configured), then run ./script/start. Everything is OK. I hope this post can help other one like me.
